Topic: Bootloader for Nano (Read 821 times) previous topic - next topic

Hello all
I got an Nano 3.0 clone, but it is not having a bootloader installed.

When I look into the hardware/bootloaders folder, I see there are many different to choose from.

If someone could tell me which hex file to install, I think I can manage to install it myself.

Best regards

Hey, it's "bipolar transistor" or "junction transistor" - "BJT" is just stupid.

RP is correct, the default Nano bootloader is the one from the Duemilanove.

I reflashed my Nano with OptiBoot (the bootloader used on the Uno) and have had no problems. I've now got OptiBoot running on all my boards & standalone chips; now I can leave the board at "Uno" and not have to switch every time I move between projects.

I do the same - all my '328P projects are bootloaded as Unos.

I understand how to put Optiboot on a 328 chip.  I use the Uno board as explained on the site.
How do you burn a new bootloader to a chip on a surface mount board such as Nano?

The exact same way. D10 on the Arduino running the bootloader upload script to the reset pin on the Nano, D11 - 13 from the uploader to pins D11 - 13 on the Nano, ground to ground, and 5v to 5v.

I use the ICSP via USBtinyISP.
(I've seen available a "Nano" that shipped/s without the ICSP header - unpopulated pads.)
